Adjustments
Marker Disk Adjustments
The aggressiveness and the mark left by the disk may be
changed by two methods:
Refer to Figure 4-1:
1. Disk Angle
To change the angle of cut, loosen the two bolts (1),
rotate the disk assembly and retighten.
2. Direction of Cut
The disk may be mounted to throw dirt either in or out
which will give different marks in different soil condi-
tions. To change the direction of cut:
a. Reverse the blade and depth band by remounting
the four lug bolts on the disk hub.
b. Reverse the angle of the assemble by removing
the adjustment bolts (2) and turning the spindle
assembly one half turn. Reinstall and tighten all
bolts.
Marker width adjustments are made by loosening the
marker tube u-bolt #(2) and sliding it in or out to the de-
sired width and by tightening the u-bolt.
Dimension (A) is measured from the center line of the
planting unit to the marker disk.
This are approximate dimensions and should be checked
in the field.
For 6-row wide, 36 inch rows, A = 126 inches.
For 6-row wide, 38 inch rows, A = 133 inches.
For 8-row narrow, 30 inch rows, A = 135 inches.
After adjusting marker, tighten u-bolt.

Meter Drive Adjustments
The alignment between the meter clutch and the input
shaft is important. If there is misalignment the meter will
not function properly. Excessive wear and damage can
also occur to the meter housings. When replacing the
meter the vertical and horizontal alignment should be
checked.
Check for Vertical Alignment
Refer to Figure 4-2:
1.
Latch the appropriate hopper into place on the sup-
port.
2. The roll pin in the end of meter input shaft should be
centered (equal distances of the roll pin should pro-
trude from both sides of the shaft).
3. Rotate the input shaft so that the roll pin is vertical.
4. Rotate the drive coupler so that the slots are vertical.
5. Release the clutch to engage the drive coupler with
the input shaft.

If the alignment is correct the coupler will engage with the
shaft freely and the roll pin will extend equally on each side
of the coupler. Disengage the clutch and check the hori-
zontal alignment.
